There's no need to switch to a revolver, unless you are doubting your auto's all of a sudden.
I have both, and carry both. My daily carry is usually a Glock .45acp, but I often switch to my Taurus 651 .357mag. I like the simplicity of the revolver (which a glock replicates to some degree) and I find I can conceal it better, but I am a better shot with my auto's.
I have more faith in a wheel gun, but enough faith in my auto's that I am not afraid to carry them, especially since I seem to shoot better with them.
